请帮助



我试图用C＃远程登录斑马打印机，然后使用我提供的值运行菜单，然后想要返回一个值。



这是我的代码到目前为止：当我使用putty进行远程登录时，系统会提示输入密码，然后在我输入密码后，我会收到菜单。所以在我的代码中，我想给出值1234作为密码，然后我想返回菜单。请帮助我卡住了:(

Please help

I am trying to telnet into a zebra printer with C# and then run through the menu with values I supply and then want to be returned a value.

This is my code thus far: When I telnet with putty, I get prompted for a password, then after i put in the password I get the menu. So in my code I want to give the value "1234" as the password and I then want to be returned the menu. Please help Im stuck :(

public static void StartClient() {
    // Data buffer for incoming data.
    byte[] bytes = new byte[1024];
    // Connect to a remote device.
    try {
        // Establish the remote endpoint for the socket.
        // This example uses port 23 on the Server.
        IPHostEntry ipHostInfo = Dns.Resolve("10.121.237.151");//Dns.GetHostName());
        IPAddress ipAddress = ipHostInfo.AddressList[0];
        IPEndPoint remoteEP = new IPEndPoint(ipAddress,23);

        // Create a TCP/IP  socket.
        Socket sender = new Socket(AddressFamily.InterNetwork, 
            SocketType.Stream, ProtocolType.Tcp );

        // Connect the socket to the remote endpoint. Catch any errors.
        try {
            sender.Connect(remoteEP);

            Console.WriteLine("Socket connected to {0}",
                sender.RemoteEndPoint.ToString());

            // Encode the data string into a byte array.
            byte[] msg = Encoding.ASCII.GetBytes("1234/n/r");


            // Send the data through the socket.
            int bytesSent = sender.Send(msg);

            // Receive the response from the remote device.
            int bytesRec = sender.Receive(bytes);
            //Console.WriteLine(msg.ToString());
            //Console.WriteLine("Echoed test = {0}",
            //    Encoding.ASCII.GetString(bytes,0,bytesRec));
            //Console.ReadLine();

            // Release the socket.
            sender.Shutdown(SocketShutdown.Both);
            sender.Close();
            Console.ReadLine();

        } catch (ArgumentNullException ane) {
            Console.WriteLine("ArgumentNullException : {0}",ane.ToString());
            Console.ReadLine();
        } catch (SocketException se) {
            Console.WriteLine("SocketException : {0}",se.ToString());
            Console.ReadLine();
        } catch (Exception e) {
            Console.WriteLine("Unexpected exception : {0}", e.ToString());
            Console.ReadLine();
        }

    } catch (Exception e) {
        Console.WriteLine( e.ToString());
        Console.ReadLine();
    }
}

推荐答案

坚持什么？你还没有解释你的问题。但是，您可能需要编写正确的Telnet客户端，而不是仅使用简单的套接字交换;请参阅 http://tools.ietf.org/html/rfc854 [ ^ ]有关协议的详细信息。

Stuck with what? You have not explained what your problem is. However, you may need to write a proper Telnet client rather than just use a simple socket exchange; see http://tools.ietf.org/html/rfc854[^] for details of the protocol.

我想要做的是，在我的代码中将服务器密码发送到服务器，选择我在连接putty时会看到的菜单项，然后为我返回一个值，我会在菜单中看到...这可能吗？

what I want to do is, in my code send the server password to the server, select a menu item that I would see when connecting with putty, and then return a value for me that i would see in the menu...is that possible?
